    I don't have any resolutions configured for Screen0, but Screen1 is the one giving me trouble. I used the device configurations reported to me by the Knoppix CD for Card0, Card1, Monitor1, and Screen1, and the X -configure settings for Monitor0 and Screen0 (and everything else). I also double-checked, and my Screen1 is running at 800x600, not 640x480 as I previously thought. I just looks really low because the other screen is running at 1280x1024. Whoops... scratch that. The other screen is running at 1400x1050 (yikes).

    By the way, sometimes I screw up the XF86Config-4 file and get two blank screens when I restart X. Is there a keyboard shortcut I can use to get into text/command-line mode from there?

    I wasted a day getting this going with even minimal success on KNX 4.0.2 till I tried using Rinks suggestion to generate a XF86Config-4 replacement file with all my hardware installed. I figured it could NOT be that easy. Apparently it is.

    Using "init 3" from a root shell to exit KDE, I ran the "X -configure" command (as root) and copied the resulting XF86Config.new file to /etc/X11 as XF86Config-4. I restarted KDE using the "init 5" command. Thinks were functional as both montiors worked, but FAR less than perfect (goofy resolution, mismatched color depth, screens went black and white when running xawtv, etc.).

    So I used XF86Config-4 files saved from separate live CD boots as a reference on what was needed; first I installed just the card and monitor i was using for monitor0. After saving the XF86Config-4 file for monitor0, I removed that card and monitor, and performed the same steps using the hardware for monitor1.

    Using the information from the two additional files, I modified the file created using "X -configure". Happy to report that things work spectacularly now.

    I may have to get an additional card now so that I can span three monitors...

    This post was invaluable in getting this going. Thanks all...
